Linshuichonetes gen. nov., a new rugosochonetid (Brachiopoda) genus from the Liangshan Formation (Early Permian) in Sichuan, China, and its ecology

A new genus and species, Linshuichonetes elfinis, belonging to the Rugosochonetidae, is described from the Early Permian (Late Artinskian or early Kungurian) Liangshan Formation of the Yangtze block. The new genus is defined externally by the presence of fine, but delayed, capillation and a weak or absent median sulcus and fold and by the presence of a distinct posteromedian sinus on the ventral umbo; and internally by a lack of median, lateral and accessory septa in the dorsal interior; absence of vascular trunks in the ventral interior and the presence of distinct radiating rows of papillae in the interior of both valves, particularly an unusual clustered arrangement of papillae on the posteromedian portion of the dorsal interior. The local environment during the deposition of the Liangshan Formation appears to have been a restricted tidal flat or lagoon which experienced frequent sealevel fluctuations associated with the onset of the Yanghsingian transgression. The new species, L. elfinis, appears to have several morphological adaptations enabling successful exploitation of this environment. It was typically a very small and thin-valved species with a high surface area to volume ratio, an advantage in an oxygen restricted environment. The small size and numerous body spinules would have aided individuals to remain suspended at the top of the fine, soft substrate. It also dominated the brachiopod assemblage in the Liangshan Formation, comprising up to 94%of specimens within a bed. These factors indicate that the new species appears to be an opportunistic species.

Training for the new work order : the adult classroom as a site of class(ed) work

This paper reports on a qualitative case study that investigated how the professional identities of trainers in the adult sector in Australia are shaped by intersecting relations of social class, ethnicity, gender and the discourses of vocational adult education. Interviews with two trainers as well as observations of them at work are analysed and presented here to illustrate how social class, considered in relation to gender and race, is played out through the trainers' identity investments in discourses of nurturance and care and economic rationalism. Such identity investments shape the relationships the trainers develop with their students and the training strategies and practices they privilege. The paper argues the need for trainers to develop critical reflective practices and to interrogate how their investments in particular classed identities shape their views about learning for work and training for work. It also argues the need for more research around social class and trainer identity within the adult sector.

Can written nursing practice standards improve documentation of initial assessment of ED patients?

Introduction: There is wide variation in emergency nursing practice in terms of initial patient assessment and the interventions implemented in response to these patient assessment findings. It is hypothesised that written ED nursing practice standards will reduce variability in documentation standards related to initial patient assessment.

Aim: This study aimed to examine the effect of written ED nursing practice standards augmented by an in-service education programme on the documentation of the initial nursing assessment.

Method: A pre-test/post-test design was used. Initial patient assessment was assessed using the Emergency Department Observation Chart. All adult patients (>18 years) who presented with chest pain and who were triaged to the general adult cubicles were eligible for inclusion in the study. Random sampling was used to select the patients for the pre-test (n = 78) and post-test groups (n = 74).

Results: There was significant improvement in documentation of all aspects of symptom assessment except quality and historical variables: pre-hospital care, cardiac risk factors, and past medical history. Improvements in documentation of elements of primary survey assessment were variable. There were significant increases in documentation of respiratory effort, chest auscultation findings, capillary refill and conscious state. There was a significant 18.3% decrease in the frequency of documentation of respiratory rate and no significant changes in documentation of oxygen saturation, heart rate or blood pressure.

Conclusion: Written ED nursing practice standards were effective in improving the documentation of some elements of initial nursing assessment for patients with chest pain. Active implementation strategies are important to ensure effective uptake of written practice standards and the relationship between nursing documentation and actual clinical practice warrants further consideration using a naturalistic approach in real practice settings.

Severity of ED : relationship to treatment-seeking and satisfaction with treatment using PDE5 inhibitors

Introduction. Research in the past 20 years has demonstrated that erectile dysfunction (ED) is an area of concern for men and their partners.

Aim. The current study was designed to evaluate the impact of the perceived severity of ED on treatment-seeking behavior and satisfaction with treatment among men with ED.

Main Outcome Measures. Participants completed a questionnaire to assess the above variables, as well as the duration of ED.

Methods. Participants were 410 men with ED who were primarily recruited over the Internet via men's health websites.

Results. The results demonstrated that men with more severe ED compared with men with milder ED were more likely to have discussed their ED with their partner and doctor, have sought assistance for their ED problem, but they were also less satisfied with the effectiveness of phosphodiesterase type 5 inhibitors, and said they were less likely to use them in the future. Men with more severe ED were also less likely to want ED medication to last for 24 hours.

Conclusions. Implications of these findings for the treatment of men with different levels of ED are discussed.

Knowledge and attitudes of ED staff before and after implementation of the emergency nurse practitioner role

Introduction
The Emergency Nurse Practitioner (ENP) role was implemented in the Emergency Department (ED) at The Northern Hospital (TNH) in April 2004. Implementation of the ENP role occurred as part of a Department of Human Services funded project to establish the ENP model as an effective and sustainable model of care delivery in Victorian EDs.

Aim
The aim of this study was to examine the attitudes and knowledge of ED medical and nursing staff prior to, and following, implementation of the ENP role.

Methods
The design was a pre-test/post-test design and the Northern Emergency Nurse Practitioner Staff Survey was used for data collection. A total of 104 ED staff completed the pre-test survey and the post-test survey was completed by 79 ED staff.

Results
The attitudes and knowledge of ED medical and nursing staff changed significantly during implementation of the ENP role. Pre-test data indicated that staff were generally supportive of the role but had a poor understanding of the requirements for endorsement and how the role would function in clinical practice. Post-test data showed significant increases in support for the ENP role, a greater understanding of the requirements to become an ENP and increased understanding of the logistics and functions of an ENP.

Conclusion
The implementation of the Nurse Practitioner role within the emergency department of The Northern Hospital, Victoria Australia has been a positive experience for both medical and nursing staff.

Gen Zeds: Arab women speaking with “still small voices”

The “Gen Zeds” of the title are female Emirati students in their early twenties at Zayed University who oscillate between the traditional Islamic culture of their families, and the highly mediated global culture they experience at university and on the Internet. In a typical week these women spend as much time on the Internet as they do in the combined activities of reading magazines, newspapers and books. They spend twice as much time on the Internet as they do watching television.

Media life among gen zeds

The ‘Gen Zeds’ of the title are female Emirati students in their early 20s at Zayed University who oscillate between the traditional Islamic culture of their families and the high technology world they experience through the media. This article looks at when, where and how these students use media and what they are looking for when they use it. The research found that these women live a highly-mediated existence, spending more than 9.9 hours on average a day with the media - more time than they do sleeping. They spend as much time on the internet as they do in the combined activities of reading magazines, newspapers and books. They spend twice as much time on the internet as they do watching television. They use different media during different parts of the day and for different reasons. The internet and the telephone were the two most preferred media. The article concludes by looking at what these women’s highly mediated lives might mean for their future.

Gen zeds : Arab women speaking with 'still small voices'

The ‘Gen Zeds’ are female Emirati students in their early twenties at Zayed University who oscillate between the traditional Islamic culture of their families, and the highly mediated global culture they experience at university and on the Inter-net. These students come almost entirely from prosperous families. On graduation, they are expected to assume leadership positions in the United Arab Emirates – a country in transition – despite living in a society that recently has not permitted women roles beyond that of mother and homemaker. This article considers whether the lessons and experiences they encounter at university – and their intense exposure to a technology-mediated world – will equip them for life in a society radically different from that of their mothers, and whether their ‘still small voices’ will be heard in a new technology economy.
